Single Transmitter (MULTI-ONE): Only one
transmitted signal on one band permitted during any 10-minute period (run
transmitter). Exception: One — and only one — other transmitted
signal (multiplier transmitter) may be used during any 10-minute period,
if — and only if — it is on a different band from the run transmitter
and the station worked is a new multiplier. The run and multiplier transmitters
are governed by independent 10-minute rules. Ten-minute periods begin with
the first QSO on a band. The log must indicate which transmitter (run or
multiplier) made each QSO. The multiplier transmitter may not call CQ (solicit
contacts).

Flex one -- run radio. computer 1 N1MM instance 1 (SO2V or SO2R on one band is ok. if you go to 2 bands 10 minute rule will apply. No one says you cant have another slice open for band awareness however but tx there and you are stuck there for 10) Flex 2 computer 2 N1MM instance 2 -- Mult radio same deal watch that 10 minute rule. You can network the two instances so the log is unified.
